Norway Joins France's 10-Nation Nuclear Deterrence Initiative as Europe Reassesses US Security Reliance
15 articles · Updated · POLITICO Europe · May 28
Norway said it will join France's initiative on how French nuclear weapons can contribute to European security and deterrence, with Prime Minister Jonas Gahr Støre announcing the move alongside President Emmanuel Macron in Paris.
10 European countries, including Norway, are now participating in the French-led effort as governments rethink defense strategy under pressure from Russia's war in Ukraine and doubts about the Trump administration's reliability.
Norway has traditionally been closely aligned with the United States, making its entry into the French initiative a notable shift even as NATO and US guarantees remain central to its security posture.
The move adds to a broader European push to strengthen regional deterrence and reduce dependence on Washington as the continent rearms against Russia.

As Europe forges its own nuclear shield, will this strengthen NATO or create a fatal rift with America?
France Extends Nuclear Umbrella to Norway: Implications for European Security and Strategic Autonomy (2026)
Overview
On May 27, 2026, Norway and France signed a landmark defense agreement, making Norway the first European country to join France’s nuclear umbrella after President Macron’s March proposal. This means that any attack on Norway could trigger a nuclear response from France, which has about 290 nuclear warheads, most of them submarine-launched. The agreement is designed to strengthen Norway’s security and add a strong layer of deterrence, while also contributing to the stability of the wider European region. This move marks a significant step in deepening European defense cooperation amid changing global security challenges.
